To all whom it may concern:

Be it known that 1, Lewis S. PnENTIss, a citizen of the United States, residing at Oklahoma city, in the county of Oklahoma and State of Oklahoma, have invented certain new and useful Improvements in Reversible Supporting-Plates for Adjustable Hinging- Strips for Doors, of which the following is a specification.

My invention relates to reversible supporting-plates for hinging-strips for doors in dwelling houses and other buildings in which the door is hinged to a vertical hinging-strip having supporting hooks secured to its rear surface with their lip or hook portions resting in seats provided therefor in hook-support ing plates secured to the studd'mg and the 'amb to su ort the wei ht of the door adjusting-bolts at the top and bottom portions of the said hinging-strip serve to hold said strip in position and adjust the same, all of which will be fully explained as we proceed.

The objects of my invention are to provide means whereby shrunken and swollen doors may be adjusted to close properly without the necessity of piecing them out or dressing them off. I accomplish these objects by the mechanism illustrated in the accompanying drawings, forming a part of this specification, in which- Figure 1 is an elevation of the inside of an ordinary door hinged with my attachments, being partly shown where the casing is broken away; Fig. 2 is an elevation of the same, viewed from within the doorway, with the door opened and. aportion of the door stop broken away; Fig. 3 is an elevation of the left side of the doorway, with portions of the door casing and the plastering removed to disclose interior parts Fig. 4 is a cross section on line :20 Fig. 1 Fig. 5 is an elevation of a portion of the door jamb, the hinging-strip and the door-stop, a portion of which is broken away; Fig. 6 is a perspective of the upper end of the hinging-strip Fig. 7 is similar to Fig. 5, except that a stub of a nail is substituted for the supporting-hook; Fig. 8 is an end elevation of the hook-supportingplate; Fig. 9 is a plan of the same as in position; for active service; Fig. 10 is a vertical section of a portion of the hinging-strip sho wing position of the adjusting bolts.

Similar characters refer to similar parts in the several views.

l ings of a door frame, in which the edges of the side casings B and C are beveled and the door is set in the thickness of the casing. The hinging-strip a is the same thickness as the door D and in width may range from one to three inches, the door being hinged to its face edge, and in the present case to swing to the left.

In constructing new buildings, in placing the studdings for the door, place two as b and b, Fig. 4 and from the inner edge of the amb c rip off a piece as wide as the hinging-strip is thick and nail it on the edge of the studding b for a ground l), to which the casing B is nailed, it being nailed also to the studding b; 0 indicates the door stop, d the outside casing, d the weatl'ier-board c the lath and e the plaster of the wall of a wood or frame building. In stone and brick buildings pieces of wood may be set in the wall to which the casing and other parts may be secured.

To support the door and the hinging-strip a said strip has set in its rear side and near each end a supporting-hook consisting of a plate member f provided with screw holes, a right-angled member f projecting from one of the sides of said plate at one of its ends and a return flange or lip f'parallcl with said plate member which is set-in flush with the surface of said hinging-strip, to which it ,is secured. See Fig. 6. To form a rest for the lip f the hook-supportinglate 9 is provided having a perforated plateody portion and from its upper and lower edges forwardly turned hooks g and g making it reversible, and when viewed from its end has much the form of the letter E with its central part removed; said plate 9 is secured, by screws, to the edge of the j amb c and to secure it more firmly an ear member h projects from its rear surface and transversely thereto and by means of the bolt h it is firmly secured to the said jamb, see Fig. 9 and to secure said hooksupporting-plate (g) to the studding l), the inner end of said plate bends outward at a right angle forming a foot 1', of equal width with the main body thereof its toe portion t having threaded perforations 1, 2 ann 3, corresponding to thick, thin and medium hingingstrips; from the back of said foot portion (2) and at right-angles thereto projects a wing i having holes for screws by which it is secured to the studding I), being set in the edge flush therewith and the foot (43) is set in the side of the studding, flush, a short portion of the 1 adjusting bolt m is passed loosely through from edge to edge of said hinging-strip and is threaded into one of the holes 1, 2 or 3 according to the thickness of the said strip a. To prevent the head of said bolt m from binding; or from wearing the hinging-strip the collar is provided and set in the edge of said strip regarded as the outer or face edge and, to secure said collar and bolt head in proper relation a face-plate 0 having" screw holes and a central adjusting-hole g is set into said hanging-strip flush with its edge and firmly secured in position that the center of said adjusting-hole g shall be directly over the head of said bolt to admit a screwdriver to the kerf in the head of said bolt for turning the same. The supporting and adjusting parts are reversible and are duplicates above and below except that the screws 8 8 should be longer than the upper ones 1" 1", because the pressure is upon the rear of the lower face plate.

To apply these attachments to the doors of old buildings, where the doors are set in, remove the casing B or C and from the jamb 0 cut a strip the thickness of the hinging-strip a, lace and secure the two hooksupporti11g-plates g; hinge the door to the hinging-strip and put it in place securing it by the upper adjusting-bolt m and by the two adjusting-bolts set the door so it will close properly.

In operation, if the door swells and thus prevents it from closing, with a screwdriver turn both adjusting-bolts until the door closes properly; if the building settles or from other causes the door binds against the casing as at D, turn the upper adjustingbolt to draw the upper end of the hingingstrip back and if the door binds at D turn the lower adjusting-bolt to draw or permit the lower end of the hinging-strip to move rearward until the door closes properly; and, in case the door shrinks reverse the operation.

My present invention is an improvement on my former patent of November 5, 1907 numbered 870,128, the present being a Sin].- pli'fication and better adaptation of the invention to old buildings.

Having thus described my invention, what I claim as new and useful and desire to secure by Letters Patent is In combination with adjustable hingingstrips for hinging doors adjustably; a reversible supporting-plate 9 having its body portion perforated for screws, its upper and lower edges turned forward and toward each other forminghooks g and g, a perforated ear projection 7L extending rearward from said body portion for securing said plate in position, a foot member t formed at right angles to said. body portion and having a lateral ear projection i by which to secure said plate to the studding, the said foot portion having threaded holes 1, 2, 8, for adjustable bolts, substantially as described.

In testimony whereof I afliX my signature in presence of two witnesses.
